Alfred Worden

Alfred Merrill Worden was an American test pilot, engineer and NASA astronaut who was command module pilot for the Apollo 15 lunar mission in 1971. One of 24 people to have flown to the Moon, he orbited it 74 times in the command module Endeavour.
Worden was born in Michigan in 1932; he spent his early years living on farms and attended the University of Michigan for one year, before securing an appointment to the United States Military Academy at West Point, New York. Graduating in 1955, he elected to be commissioned in the United States Air Force, though he had no piloting experience. He proved adept at flying fighter planes, and honed his skills, becoming a test pilot before his selection as a Group 5 astronaut in 1966. He served on the support crew for Apollo 9 and the backup crew for Apollo 12 before his selection for the Apollo 15 crew in 1970, with David Scott as commander and James Irwin as lunar module pilot.
After Apollo 15 reached lunar orbit, and his crewmates departed to land on the Moon, Worden spent three days alone in the CM, becoming in the process the individual who traveled the farthest from any other human being, a distinction he still holds.
